Fewer people in fewer countries want to kill Canadians. Even fewer still want to invade Canada. We're a polite, sane society whose entire army can fit in Toronto's Skydome. You're the loud, puking drunk who thinks you're great at everything and better than everyone. 10+ years have passed since 9/11 and you have learned nothing and changed nothing.
Who the fuck would want to invade a country that their greatest national resource is fucking snow? The herpes must have gone to your brain.
Actually, we have much of the world's oil. In fact, an estimated 178,900,000,000 barrels which puts Canada number 2 behind Saudi Arabia. We just don't go around bragging about it.
